A budget is only as good as the quantities behind it. COMET Estimating LTD helps contractors, builders, developers and property owners in the UK turn drawings and specifications into measured quantities and cost information that can be used for pricing, budgeting and early decision-making. Each measurement is checked back to the documents, so the figures follow the scope that has actually been drawn and described, not an assumption about it.
Drawings rarely tell the whole story on their own. A detail may be shown on one sheet and contradicted on another, or a specification note may have no matching item in the schedule. Reading the documents together, and thinking about how the work will actually be built, makes it easier to spot gaps, query inconsistencies and flag cost risks while the design can still be adjusted. Any estimate is based on the information available at the time, so assumptions and exclusions are set out clearly rather than buried.
Measured quantities and early cost planning show where a budget is thin before money is committed. Gaps are far easier to deal with at design stage than once work is under way.
A clear breakdown of quantities and costs helps you price a job with more confidence and see where your numbers sit against the scope. That makes it easier to avoid pricing too low to cover the work or too high to be considered.
Reviewing drawings and specifications for quantities often turns up clashes, omissions and unclear scope. Raising them before construction begins saves time and avoids disputes later.
Clients, lenders and project teams can make decisions with a better understanding of what a scheme is likely to cost. Costs still move with design changes, market conditions and site conditions, but a reasoned estimate gives everyone a common starting point.
01
Send your architectural, structural and MEP drawings, along with any specification or scope documents, through our upload system. The fuller the information, the fewer assumptions the estimate has to carry.
02
We review the scope of your project and send a quotation setting out the fee and the expected turnaround time. You can see both before any work begins.
03
Once you approve the quotation, we confirm the project details and timeline with you directly. Measurement and pricing then start.
04
You receive a structured cost report, suitable for tendering, budgeting or discussions with a funder. If you have questions or need to update the information, we're available to discuss them.
Your quotation sets out the fee and the expected turnaround before any work begins, so you can plan your tender or budget deadlines around a known date.
Cost information is organized so it can be used straight away for tendering, budgeting or discussions with a funder, without having to untangle a confusing spreadsheet to find what you need.
Quantities are measured and priced with an eye to how the work is built, covering materials, labour and the practical points that affect cost, not just the headline figures on the drawings.
Common Issues Caused by Poor Estimating
Get accurate estimates that improve your bid quality and help you secure more projects with confidence.
We want to be a quantity surveying and estimating partner that contractors, builders, developers and property owners are glad to return to. Our standard is simple: every client should understand what the figures cover, what they assume, what they leave out and how they were reached. As projects grow more complex, we aim to bring clarity, consistency and practical value to every estimate we produce, whatever its size, scope or location.
Our mission is to provide careful, well-organized cost estimates that help clients plan budgets and tenders with a clearer picture of the numbers. We combine detailed takeoffs with a practical understanding of how work is built, and we set out our assumptions and exclusions plainly, so each cost report can be followed from tender stage through to the start of construction. We would rather flag gaps early than find them later.
Contractors, builders, developers, subcontractors and property owners all use it. It is most useful early on, when the design and scope can still change without much disruption.
The fee depends on the project's size, complexity and the documentation involved. We review your scope first, then send a quotation with the fee and expected turnaround before any work begins.
It depends on the size of the project, the complexity of the drawings and the services needed. The expected timescale is confirmed in your quotation before work starts.
No. An estimate reflects the information available at the time, and costs can move with design changes, site conditions, labour and material prices, and market conditions. It gives a reasoned starting point, not a fixed price.
Absolutely brilliant! Spot-on estimates, quick turnaround, and zero hassle. Honestly, I wouldn't go anywhere else.
